Abstract: 982,007. Semi-conductor devices &c. SIEMENS-ELECTROGERATE A.G. May 16, 1961 [Aug. 3, 1960], No. 12482/64. Divided out of 980,458. Heading H1K. In an array of thermoelectric elements for heat, cold or power generation, the elements are interconnected on one side of the array by copper bridges which are held in a support by a common layer of insulating material extending around their marginal regions, the surfaces of the bridges remote from the elements being in direct contact with a heat exchange fluid. As shown in Fig. 1, elements 31 are connected by bridges 32, 33 sealed in glass plates 36, 34 the peripheries 38, 45 of which are sealed to the side walls 37, 46 of the evaporator and condenser chambers 39, 47 of closed evaporating- condensing heat transfer systems. These side walls are sealed by glass annuli 54, 55 to further walls 56, 57 the upper and lower edges of which are welded to an annular wall 58 through which extends a vacuum connection 59. Thus the chamber 60 containing the elements can be evacuated. The heat exchange surfaces of the bridges can be recessed or finned. Instead of being located in a vacuum chamber 60, the elements can be embedded in a block of sealing compound such as tetrafluoroethylene which also encloses the bridges in place of the glass plates. As shown in Fig. 5, elements 71 are connected by bridges 72, 73 on the heatdissipating and heat-absorbing sides, the former being cooled by the evaporator 77 of a secondary heat transfer system and the latter having fins 81 extending into a duct 82 traversed by hot gas. Bridges 72 are mounted in a glass plate 74. This arrangement generates power.

Loud-speakers ; magnetic instruments. - In order to improve the efficiency of a sound-reproducer such as a loud-speaker, and to effect a more correct rendering of the varying tones of speech and music, the electromagnet, by which the diaphragm is vibrated is provided with a number of separate windings, mounted on the same pole-pieces each of which windings is responsive to a particular range of frequencies. These windings may be arranged in parallel or in series, and act conjointly. Fig. 1 shows a construction of receiver in which the magnet poles 11, mounted on a plate 9 which is rotatable to permit of adjustability with respect to the diaphragm 8, are provided with two pairs of coils 16, 18. The coils 16, which are in series with a .condenser 20, are resonant to high frequencies, :and the coils 18 to low frequencies. The coils .are connected in parallel as shown in Fig. 2, which shows the receiver in the plate circuit of a valve 21. The condenser 20 may be omitted. In an alternative arrangement, as shown in Fig.4, the coils 16, 18 are in series, and a condenser 20 is connected in series with the high frequency - section. The Specification, as open to inspection under Sect. 91 (3) (a) describes also an arrangement wherein the manner in which the windings are connected together may be changed by means of a switch, so that the impedance of the reproducer may be made to match the impedances of different amplifying valves by which it may be operated. Fig. 5 (Cancelled) shows an arrangement in which the pole-pieces 11 of the reproducer are wound with coils 22, 23, so connected with a push-pull switch 24 that they may be connected either in series or in parallel. The combined impedance of the coils may thus be changed when - necessary. A switch may also be provided for the arrangement of windings and condensers shown in Fig. 1. This subject-matter does not appear in the Specification as accepted.
